The shuttlepod takes considerable damage from being shot up by the P-51 fighters. Yet in "Minefield", we find that the shuttlepods can withstand small nuclear explosions from close range. I find it hard to believe they would be vulnerable to machine guns.

Great Moment :

Seeing the White House with Nazi symbols on it. This was a very cool "oooo!" moment!

Body Count :

About half a dozen German soldiers shot by the resistance, plus at least four more blown up in the shuttle. One of the aliens is killed, along with the two resistance fighters and several more German soldiers. We see a German soldier murder an American whilst searching through a house. Daniels appears to die, though it's hard to tell with him.

Factoid :

There was much fan speculation at the end of season 3 that the mysterious alien was a Reman. As it turns out, they are actually a new never before seen species involved in the temporal cold war.

This is the first episode of Enterprise written by Manny Coto after he rose to become co-executive producer.

Plotline

Archer and Enterprise find themselves on an alternate Earth of the 1940s, in which the Germans are in the midst of conquering North America thanks to the assistance of some aliens. Things are further complicated when Silik is found aboard Enterprise, stealing a shuttle to escape to the planet, and a badly injured Daniels appears to inform the crew that the Temporal cold war has erupted into an all out conflict in which each faction is trying to re-write history to erase their enemies from existence.
